Your kidneys are two bean-shaped organs that filter blood, and remove waste and extra fluid from the body. They also balance water, salts and minerals in the blood to allow nerves, muscles, and other tissues in your body to work normally. Some foods place stress on the kidneys, causing damage, and some foods may boost the performance of the kidneys.
The foods below generally support healthy kidneys, but not all of them are suitable for people who have kidney disease:
Water is the most important drink for the body. The cells use water to transport toxins into the bloodstream and filter the toxins out of the body through urine.
Salmon, tuna and other cold-water, fatty fish that are high in omega-3 fatty acids may reduce fat levels in the blood and slightly lower blood pressure.
Sweet potatoes may help balance the levels of sodium in the body and reduce its effect on the kidneys. Sweet potatoes are high in potassium so anyone who has kidney disease may wish to limit their intake of this vegetable.
Dark leafy greens, such as spinach, kale, and chard contain a wide variety of vitamins, fibers and minerals. These foods are also high in potassium, so may not be suitable for people on a restricted diet or on dialysis.
Berries are a great source of nutrients and antioxidants. Enjoy strawberries, blueberries and raspberries to satisfy sweet cravings.
Apples contain an important fiber called pectin, that may help reduce risk factors for kidney damage, such as high blood sugar and high cholesterol.
